Digital Image Analysis for Defence

Accessing invaluable digital image and video information

Sytech use the very latest forensic techniques to recover and analyse images and video stored on digital cameras of all types. Even deleted material can be recovered, so there’s very little that we can’t give you access to.

In addition to the actual image and video, we retrieve a wealth of evidentiary data in the form of Metadata.

Metadata is the extra information stored within the media and is commonly referred to as EXIF (Exchangeable Image File Format) Data.
EXIF Data is not usually viewable by ordinary means, but through our analysis we can reveal and document information such as:

Digital Camera Information
Owner InformationCamera SettingsThis includes static information such as the camera model and make, and information that varies with each image such as orientation (rotation), aperture, shutter speed, focal length, metering mode, and ISO speed information.Date and time informationDigital cameras will record the current date and time as set by the Camera’s internal time, which in turn is set by the user – and this information is saved to the Metadata.Geolocation/Geotagging dataThis data usually consists of latitude and longitude coordinates, though they can also include the extremely accurate GPS time and date, altitude, bearing, distance, accuracy data, place names and weather.

Identifying data manipulation

As with all evidential-based data – at the same time as we are retrieving data, it’s also important that we verify its authenticity. With increasingly sophisticated editing and manipulation software available to consumers, such as Adobe Photoshop and other free variants, we can’t rely purely on what we see – it’s imperative that everything is digitally analysed to also confirm its authenticity.

And this procedure applies to a number of devices – digital cameras, but also mobile phones, PC’s, memory cards and even the internet.

All recovered materials will be validated as to their authenticity and provenance.
